No one likes mosquitoes. And since only one bite from an infected one can spread heartworm in our dogs, we have to be doubly aware of how to prevent being bitten by them. The New York Times had an interesting piece that looked at the effectiveness of using wind—in the form of a fan—to deter flying pests [4]from landing on you or on your dog. What makes the fan an effective deterrent is that it “dilutes and disperses” carbon dioxide that we, and our dogs, exhale. CO2 is the major chemical that attracts mosquitoes! Entomologists at Michigan State University who studied this link concluded “fan-generated wind should be pursued as a practical means of protecting humans or pets from mosquitoes in the backyard setting.”
